Just one week to go to the London marathon now and hopefully all of your training is done and dusted.
You are fit and strong and ready for what is going to be thrown at you on the day. You have nearly finished tapering off your training now and it might be that you are thinking maybe just do a few more runs as you can't believe you don't need just a few more miles under your belt.
Avoid the temptation - a couple of light runs this week is all that you need. This isn't much you can do now to change what will happen on the day. Stuffing a few extra sessions in last minute is worse that cramming for exams - and that never did much good - trust me I tried! All you can do is leave yourself tired for the big day and do you really want that to catch up with you 20-odd miles into the race.
I have heard of people who rent piles or dvds or have decide to start writing a book just to stop themselves doing the training they know isn't going to help in the last few days.
What lengths have you gone to to avoid overtraining the week of a race?
Good luck to one and all who are running, may you get the times that you want, raise plenty of money for charity and have lots of fun.
